“…Single Leg Matrix Converter is dedicated for supplying of two phase induction motor. Model of such a motor is known [13]- [15], [17]- [19]. So, the electric machine being considered may be described by the following set of ordinary differential equations in the stator reference coordinate frame under the commonly used simplifying assumptions:…”

The paper deals with the novel supply system for two phase induction motor. The system comprises just single leg of matrix converter, and features by reduced number of active and passive components of the supply unit. In comparison to VSI one-leg inverters with rather bulky smoothing capacitors, direct matrix converters operate without DC-link circuit. Analysis using computer simulation under both passive R-L and motoric load is given in the paper.

“…It utilizes the concept of switched capacitor which makes use of four thyristors which forms a H-bridge circuit and a single capacitor for each rotor phase. The complementary switch pairs are switched using a PWM strategy [5]. The main drawback of this method is the usage of more number of switches and three capacitors in the rotor circuit which are costly.…”

The paper proposes a novel method for improving performance of a Three Phase wound rotor induction motor using an indirect reactive current control scheme in the rotor. A 3 phase VSI with a dynamic capacitor is connected in the rotor circuit for controlling the reactive current in the rotor. The dynamic capacitor is an Hbridge switch with a capacitor in which the duty ratio of the Hbridge circuit is varied in order to change the capacitance value dynamically. The proposed technique is simulated in MATLAB 7.6 / Simulink environment. The result that obtained from the proposed method is compared with secondary impedance control scheme and the performance parameters such as the torque, power factor and efficiency are obtained. In addition to improving performances, as the proposed method uses only one capacitor in the rotor where as against three capacitors are used in the rotor impedance control scheme. The result has shown improved performance and cost effective by the proposed scheme.

“…The induction machines are suitable for operation through the inverter transducers, because the winding insulation of standard induction motors tolerates certain voltage overload but at higher speeds of rotation, that is, higher frequencies; they have higher noise level and additional losses [2][3][4], which affect the motor output torque, depending on the regulation range of the speed of rotation and power factor correction [5][6][7][8][9]. The induction machines can be connected to transducers for the purpose of asymmetry elimination and electric networks harmonics reduction [10,11].…”

The paper presents a new approach in the analysis of a transient state in a system where the feeding source is a transducer-IGBT inverter and load is introduced through the induction motor with itsR-Lparameters. Induction motors with different parameters of powers and power factors are tested. MATLAB simulation of the three-phase inverter that feeds the induction machine has replaced the missing lab equipment with which mathematical model of this system was verified. According to the selected parameters of the inverter and induction machine and through the simulation in the MATLAB program, the results are obtained in the form of diagrams that verify the model of a transient state of the induction machine operation when it operates as a motor which is presented as a variableR-Lload. The transient process of the system three-phase bridge inverter whose active-inductive load is the induction machine in the conditions of the change of the load parameters is analyzed. The model of the transient process in the system formed by the inverter in PWM (Pulse Width Modulation) converter and induction machine is developed in the time domain and phase coordinates.
